Bottom bracket for Epic

Greddyl30pjg

hi,
Bought a 2004 epic not long back, the pedals creek under pressure ...im presuming its the bottom bracket-is there a way of determining the size without taking it apart?

Are there any checks i can do to make sure im diagnosing it right?

Are they easy to replace if it is the bracket. I realise that the correct tool is needed, but other than that is it leterally slip out and slide new one in?

Help much appreciated!

I am reading in the technical specification that says 68mm shell and a 133.5mm spindle.

where? mmm ah there on the top speced bike with the crankset that does not exist.

and that is not correct info as the HT2 cranksets do not use Octalink splines.

also there is not an Octalink BB with a spindle that long.

but again you are just reading the info given for one version. which happens not to be the same spec as the bike in his sig.

They are shimano XTR and thinking about it, on my 2004 stumpy's cranks (the originals) they say hollowtech even though they are octalink :?

the Octatlink Specialized Strongarm 7050 cranks.

Should be 113mm Octalink BB as found on the 2003 year Epic.

cheers again-that was helpfull.....in particular the article mentions that creeking can be due to loose spokse! Ive nipped and bought a spoke key today to tighten them as they became loose after yesterdays ride. Ill take it for a spin tomorrow to see if thats cured the problem...although it did seem to coming from the pedal area and it did seem to creek everytime i applied alot of pressure...we'll see!

Hopefully the tightening of the spokes will make the wheel run true again too as it seemed buckled!! Ive got good quality mavic rims and ive been riding bridle paths for the last week so i could not of buckled it ...must be something to do with the spokes coming loose??!
